A HUP is reported whenever there is no client listening on the other side

uterm_input_uxkb: update leds to match keyboard state
Upon device wakeup or led state changes, we update the keyboard LEDs to
match the new xkb state.
This means that every kmscon instance retains its own LED state, in the
users eyes. In other words, if you had Num Lock set on one kmscon, switched
to an X VT where it's off, and come back, then Num Lock will be set as
when you left. This is what X server, linux VT, etc. do.
Note that since we need to write the LED events to the evdev devices, we
need to open them RDWR. But since we don't really care what happens to
that write(), that's fine.
Also note that this means NumLock is off by default, which might be
annoying. We need to think how to get some 'setleds' or 'numlockx'
equivalent functionality.

uterm_input: remove supporting code for updating LED state
Before we transitioned to xkbcommon, we had some code that, upon
returning from a VT-switch, looked at the evdev led state and updated
the keyboard modifier state accordingly. So if we returned and NumLock
was on, we adjusted ourselves to that. That was pretty cute.
xkbcommon however doesn't support updating the state by LEDs like that.
Normally, the state of the LEDs is derived from the modifiers; going the
other way is tricky, error-prone and not used much. What we should be
doing is updating the LEDs according to *our* state.
This commit does the part of removing the unused dead code.

We do the same for the model field, instead of hardcoding "evdev". The
